The invention of the camera goes far into the past . In the 1500s , men were experimenting with cameras that made images . But it was not until the early 1800s that man found a way to make the pictures permanent . Even then , photography was a new field . Most families had their pictures taken by a photographer . People did not own cameras because taking pictures and developing the film were too difficult .

In 1884, George Eastman changed photography by inventing a kind of film that fit into a small camera . Because the new film was easy to use , many people began to buy cameras. When they had used up their film , people returned their cameras to the factory , There , the film was developed , and pictures were printed . Then more film was put into the cameras , which were sent back to the owners , along with their pictures .

Eastman’s camera made it easy to take pictures . Today’s cameras are even easier to use , and people can put in their own film . Photography has become a growing hobby .

There are also many new jobs in the field of photography . One of the most important kinds of work is in news reporting . Newspapers, magazines , and television all need pictures to tell their stories . Photographers aid scientists by taking pictures through microscopes and telescopes . Deep-sea divers take pictures of ocean plants and animals , while astronauts take their cameras into space . Man finds new uses for the camera every day .
